IMPROVEM ENT IN PLOWS.

Specification forming part of Letters Patent No. 26,655, dated January 3, 1860.

To all whom it may concern Be it known that I, HENRY F. GROMWELL, ofOynthiana, Harrison county,Kentucky, have invented a certain new and useful Improvement in Flows; and I hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, makingpart of this specification, and in whicht Figure 1 is a perspective view. Fig. 2 is a view of under side, showing adjusting device. Fig. 3 is a section atw m, Figs.2 and 4. Fig.4 is an elevation of landside.

A is a flange projecting inwardly from the a side of the bar B, and having two oblong holes or slots, at. The upper land-side corner of the Wing O has also a slot, 0.

D are short bolts countersunk into the Wing O, and passing through the slots at in the flange A, beneath which they are secured by nuts 0!.-

the form of a cylindrical segment, so that the wing inevery position of adjustment possesses a firm and solid bearing both upon the bar and.

upon the sheth. By this means the frequent necessity of drawing out or relaying the working-edge of the wing is avoided. The flange Agreatly s'tiffens the bar B in a lateral direction.

I do not claim to be the firstto construct a plow with an adjustable Wing or mold-board,

but in y arrangement of parts is such as to give to an implement possessing such adjust-ability greater economy of construction as well as superior compactness, strength, and durability. I claim as new and of my invention herein and desire to secure by Letters Patent-- The described arrangement of the cylindrically-curved frame-timber 0r sheth E, wing 0, flange A, bar B, slots a and c, and boltsD and D, the whole being constructed and combined in the manner and for the purposes set forth. In testimony of which invention I hereunto set my hand.
